摘要： A powertrain is provided with an input clutch that is disengagable to allow a transmission input member to rotate independently of engine speed under power of a motor and provide an alternative way to power vehicle accessories otherwise driven by engine torque, while still allowing the motor to start the engine. A powertrain having a parallel combination of input clutches including a friction input clutch and a selectable one-way clutch is provided, as well as a method of control of such a powertrain. Another method of controlling a hybrid vehicle powertrain includes starting the engine via torque from a motor with the input clutch biased in an engaged position. If vehicle operating conditions are more efficiently met without operating the engine, the input clutch is disengaged to so that torque is provided only by the motor to the output member and to vehicle accessories operatively connected to the input member.
